FIELD OF THE INVENTION

The present invention relates to a package of sheet-type patches whichare applied to the face, and to a method for producing the same.

BACKGROUND OF THE INVENTION

Various sheet-type patches have heretofore been proposed, which areapplied to the face portion, for example, under the eyes. Thosesheet-type patches are produced by forming a pack agent layer on anappropriate substrate, for example, of non-woven fabric, followed bycovering the layer with a liner or support.

For packaging those sheet-type patches, employed is a method ofcompletely cutting a sheet comprising a pack agent layer formed on asubstrate and covered with a liner or support into individual patches,followed by packaging the resulting individual patches in packagepouches. Alternatively, also employed is another method of half-cuttingthe same sheet to form patches as supported on the liner or support thatis not cut (see FIG. 2).

However, where the sheet-type patches are completely cut out along withthe liner or support into individual ones and the individual patches arepackaged in package pouches, the packaged sheet-type patches will movein the package pouches. In particular, where a plurality of patches arepackaged in one package pouch, there occurs a problem that the patchesadhere to each other in the pouch.

On the other hand, where the sheet is half-cut to form patches assupported on the liner or support that is not cut, the substrate and thepack agent layer cut off from the sheet shall be wasted. In addition, inthis case, the size of the package pouches to be used must be large.Moreover, the working conditions for half-cutting the preformed sheetmust be strictly controlled. In particular, where the pack agent in thepreformed sheet contains a water-soluble polymer compound as crosslinkedwith a polyvalent metal, it is difficult to half-cut the sheet intoseparate patches and to trim the patches, if the crosslinking in thepack agent layer is not fully completed. For these reasons, thehalf-cutting and packaging method is problematic in that the productionefficiency is very poor and that the size of the package pouches to beused must be large. In addition, where a silicone-processed, peelablefilm are used as the liner for the patches, there also occurs a problemthat the pack agent layer itself will be peeled off while trimming, andthat, after packaged, the patches will move in the package pouches.

The object of the present invention is to improve the productionefficiency in the process of producing sheet-type patches and packagingthem, thereby making good use of raw materials for packaged sheet-typepatches. Another object of the invention is to provide packagedsheet-type patches which do neither move nor adhere to each other in thepackage pouches, and to provide a method for producing them.

SUMMARY OF THE INVENTION

In the invention, sheet-type patches each comprising a pack agent layerformed on a substrate and covered with a liner layer are packaged in apackage pouch while they are fixed onto the inner surface of the packagepouch via the liner layer.

The package of sheet-type patches of the invention can be produced, forexample, by fixing sheet-type patches, which are prepared by forming apack agent layer on a substrate, covering it with a liner layer, andthereafter cutting the thus-coated substrate into separate patcheshaving a desired shape, onto the inner surface of a packaging film viathe liner layer of each patch, by means of an adhesive or electrostaticforce, followed by sealing the film to produce a package pouch.

Specifically, in the invention, a sheet having a structure ofsubstrate/pack agent layer/liner layer is completely cut into individualpatches having a desired shape, and the resulting patches are directlyfixed onto the inner surface of a package pouch, whereby the patches areintegrated with the package pouch.

According to the present invention, the process of producing sheet-typepatches and packaging them is much simplified, and the productionefficiency in the process is much improved. In addition, the rawmaterials for the patches are not wasted. Moreover, in the package ofsheet-type patches of the invention, the patches do neither move noradhere to each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The material for the substrate for the sheet-type patches of theinvention is not specifically limited. Any material usable for producingordinary sheet-type patches is employable herein, including, forexample, knitted or woven fabrics of flannel, staple fiber muslin;various non-woven fabrics; paper, plastics, etc.

The pack agent composition to be applied on the substrate by dipping orcoating is not also specifically limited, and may be any ordinary one.It comprises, for example, any of moisturizers such as glycerin,sorbitol, polyethylene glycol; various cosmetically-active ingredientssuch as keratinization retardants, wrinkling retardants, whiteningagents; other pharmaceutical ingredients; water-soluble polymercompounds crosslinked with poly-valent metals and containing water, oilycomponents and others; film-forming compounds such as polyvinyl alcohol,polyvinyl pyrrolidone, polyvinyl acetate emulsion, carboxymethylcellulose, along with a vehicle of an inorganic powder of kaolin, talc,bentonite, titanium dioxide, zinc oxide and the like.

The water-soluble polymer compounds usable in the pack agent compositionin the invention are not specifically limited, but preferred arepoly(meth)acrylic acids. The poly(meth)acrylic acids referred to hereinare meant to include homopolymers and copolymers of (meth)acrylic acid,homopolymers and copolymers of (meth)acrylates, copolymers of(meth)acrylic acid and (meth)acrylates, their partially-neutralizedproducts, and their mixtures. The (meth)acrylic acid means acrylic acidand methacrylic acid. The type of the salts for poly(meth)acrylates isnot specifically limited, but generally used are sodium salts.Preferably, those water-soluble polymer compounds are in the compositionin an amount of from 1 to 30% by weight, more preferably from 2 to 15%by weight of the total composition. Also preferably, the water-solublepolymer compounds are used in the form of their crosslinked products,especially those with poly-valent metals.

Water-soluble salts are preferred as the poly-valent metal salts used asthe crosslinking agents for the water-soluble polymer compounds, whichinclude, for example, calcium chloride, magnesium chloride, aluminiumchloride, potash alum, ammonium alum, iron alum, aluminum sulfate,ferric sulfate, magnesium sulfate and the like.

The amount of the crosslinking agent to be used may be generally from0.01 to 5 equivalents, but preferably from 0.1 to 2 equivalents,relative to one equivalent of the crosslinkable site of thewater-soluble polymer compound. If the amount of the poly-valent metalsalt used is smaller than 0.05 equivalents, it will be sequestered andcould not act to gel the polymer. On the other hand, if the amount islarger than 5 equivalents, the degree of crosslinking of the polymerwill be too high, thereby causing separation of water from thecrosslinked polymer.

As the active ingredient, one or more of methyl salicylate,indomethacin, 1-menthol and the like that are generally used in the artmay be formulated in the composition. For skin-care purposes, any ofvarious cosmetically-active substances, moisturizers, animal andvegetable extracts, vitamins and the like that are used in conventionalcosmetics may also be formulated in the composition. Preferably, theamount of the active ingredient is from 0.01 to 20% by weight of thetotal composition.

As preferred examples of the oily component to be in the composition,mentioned are primary alcohol-fatty acid esters of the following generalformula:

R₁—COOR₂

wherein R₁ represents a linear or branched alkyl group having from 2 to18 carbon atoms; and R₂ represents a linear or branched alkyl grouphaving from 1 to 18 carbon atoms. Of those, especially preferred areisopropyl myristate and octyldodecyl myristate, as they have goodcapabilities of improving the releasability and endermic absorbabilityof active ingredients, and they irritate little the skin. The amount ofthe oily component is preferably from 1 to 20% by weight, morepreferably from 2.5 to 10% by weight of the total composition.

Since the water content of the pack agent composition is high, silica ispreferably used as an oil-gelling agent in the composition. As thesilica, preferred is anhydrous light silica, especially that having amean grain size of primary grains of from 1 to 500 mμ, more preferablyfrom 5 to 100 mμ. The oil-gelling agent stabilizes uniform dispersion ofoily components in the pack agent composition, while preventing the oilycomponents from bleeding out. Containing the oil-gelling agent,therefore, the composition gives no sticky feel to the skin and iscomfortable. Preferably, the amount of the oil-gelling agent to be addedis from 1 to 15% by weight, more preferably from 2 to 10% by weight ofthe total composition.

Apart from the components mentioned above, the pack agent composition ofthe invention may optionally contain one or more moisturizers generallyused in ordinary pack agents, in an amount of from 5 to 40% by weight ofthe total composition. In addition, the composition may further containone or more inorganic powders of kaolin, talk and the like, in an amountof from 0 to 30% by weight of the total composition. Further, in orderto modulate the physical properties (flexibility, stickiness, shaperetentiveness, etc.) of the plaster-like composition, any suitablepolymer compounds such as polybutene, acrylic resin emulsion and thelike may be added to the composition.

The pack agent composition for use in the invention may contain watergenerally in an amount of not smaller than 30% by weight, but preferablyfrom 40 to 80% by weight.

In the invention, the pack agent composition is applied onto a substratesuch as non-woven fabric or the like by dipping or coating to form apack agent layer thereon, and the pack agent layer is covered with aliner layer to prepare a long sheet for patches. Next, the long sheet iscompletely cut into patches having a desired shape, and the resultingsheet-type patches are fixed onto a packaging film. Next, the packagingfilm is sealed into pouches. In that manner, the patches are integratedwith the package pouches.

The packaging film for use in the invention is not specifically limited,but, in general, used are plastic films.

Plastic materials suitable for forming the plastic films may bethermoplastic resins, which include, for example, polyolefins such ascrystalline polypropylene, crystalline propylene-ethylene copolymers,crystalline polybutene-1, crystalline poly-4-methylpentene-1, low-,middle- or high-density polyethylenes, ethylene-vinyl acetate copolymers(EVA), ethylene-ethyl acrylate copolymers (EEA), ion-crosslinked olefincopolymers (ionomers); aromatic vinyl polymers such as polystyrene,styrene-butadiene copolymers; halogenovinyl polymers such as polyvinylchloride, vinylidene chloride resins; nitrile polymers such asacrylonitrile-styrene copolymers, acrylonitrile-styrene-butadienecopolymers; polyamides such as nylon-6, nylon-66, para- or meta-xylyleneadipamide; polyesters such as polyethylene terephthalate,polytetramethylene terephthalate; various polycarbonates; polyacetalssuch as polyoxymethylene.

Films of those plastic materials may be non-oriented ones, or may bemonoaxially or biaxially oriented for use in the invention.

The plastic films which are used as packaging films in the invention maybe single-layered ones or may be multi-layered laminates composed of twoor more of those films. If desired, one or more of those plastic filmsmay be laminated with metal foil of aluminium or the like, and/or withpaper, cellophane or the like.

Preferred are multi-layered laminate films of the plastic films thatcomprise an interlayer of aluminium foil(Al). As embodiments of thelayer constitution of the laminate films, mentioned are 1) polyethyleneterephthalate (PET)/Al/ionomer resin/copolypropylene (CPP); 2)PET/Al/low-density polyethylene (LDPE)/CPP; 3) PET/Al/linear low-densitypolyethylene(L-LDPE)/CPP; 4) nylon(Ny)/Al/ionomer resin/CPP; 5)Ny/Al/LDPE/CPP; 6) Ny/Al/L-LDPE/CPP, etc.

As one embodiment of fixing sheet-type patches onto the packaging film,mentioned is a method of using an adhesive for the fixation. Onepreferred mode of this embodiment comprises the steps mentioned below.

1) An adhesive is partly applied to a packaging film in the area towhich sheet-type patches are fixed, and sheet-type patches as cut tohave a desired shape are fixed onto the film at the adhesive-coatedposition, via the liner layer of each patch.

2) Next, the packaging film is sealed to form a package pouch in whichthe patches are integrated with the package pouch.

For fixing the patches onto the packaging film, it is desirable that anadhesive is partly applied to the packaging film around the center ofthe part at which each sheet-type patch is fixed (see FIG. 1). Theadhesive may be spotwise or spirally applied to the desired position ofthe film at which each sheet-type patch is fixed, or may be appliedthereto by spraying. Alternatively, an adhesive may be applied to theliner layer of each sheet-type patch as cut to have a desired shape, andthe patch may be fixed onto the packaging film. The adhesive to be usedfor the fixation of the sheet-type patches is not specifically defined,but preferred are hot-melt adhesives, such as olefinic adhesives, rubberadhesives and the like.

In another embodiment of fixing sheet-type patches onto the packagingfilm, employed is electrostatic force. One preferred mode of thisembodiment comprises the steps mentioned below.

1) At least one of the liner layer of each sheet-type patch and thepackaging film is electrostatically charged.

2) The sheet-type patch as cut to have a desired shape is fixed onto thepackaging film by means of electrostatic force.

3) Next, the packaging film is sealed to form a package pouch in whichthe patches are integrated with the package pouch.

In this case, the liner layer of each sheet-type patch and the layer ofthe packaging film to be the inner surface of the package pouch must bemade of dielectrics. For this, at least one of the liner layer and thepackaging film shall be electrostatically chargeable. The liner layer ofthe sheet-type patch may be electrostatically charged, while it is stillin the non-cut long sheet to be cut into patches. It may also becharged, after the patches are cut out of the long sheet to have adesired shape.

In the method of fixing the sheet-type patches onto the packaging filmby means of electrostatic force, the liner layer of the patch and/or thepackaging film may be entirely and uniformly charged. Therefore, theworking efficiency in the method is good. In particular, the method isadvantageous when a large number of sheet-type patches are packaged inone package pouch. In addition, in the packages formed in this method,not only the sheet-type patches are fixed onto the packaging film byelectrostatic force, but also the upper-side and lower-side film to formthe package pouch are attracted to each other by electrostatic force.Therefore, in the method, sealing the film into the package pouch doesnot require any external force to degas the pouch. Accordingly, in themethod, it is possible to easily degas the package, without crushing thedelicate sheet-type patches therein, to thereby reduce the bulk of thepackage.

The package of sheet-type patches of the invention can be produced byoverlaying another packaging film on the packaging film, which hassheet-type patches as fixed thereon, to form a package pouch, followedby heat-sealing the edges of the films. Alternatively, one packagingfilm which has sheet-type patches as fixed thereon may be folded to forman envelope, and the open edges of the envelope may be heat-sealed intoa package pouch.

The sheet-type patches to be packaged herein may be prepared by cuttinga long sheet for the patches in any desired shape. For example, forskin-care use for treating the areas outside and under the eyes, thepatches preferably have the shape as illustrated in FIG. 5.

For the package of a pair of bilaterally symmetric patches, which arefor the areas outside and under the eyes and for the areas around thenasolabial grooves, it is desirable that the pair of bilaterallysymmetric patches are fixed onto the inner surface of the packaging filmin such a manner that they face to each other (see FIG. 6). Where thepair of such patches are positioned in that manner, the space for thepatches may be reduced. If desired, a large number of such patches maybe packaged in one package pouch.

Now, the package of sheet-type patches of the invention is described inmore detail hereinunder with reference to the drawings attached hereto.The examples are given solely for the purpose of illustration, and arenot to be construed as limitations of the present invention, since manyvariations thereof are possible without departing from its spirit andscope.

EXAMPLE 1

FIG. 1 shows one embodiment of the package of sheet-type patches of theinvention, in which the numeral reference 1 is a sheet-type patch, 5 isan adhesive, 6 is a packaging film, 9 is a package pouch, and 10 is apackage of sheet-type patches.

In this embodiment, the patch 1 is composed of a non-woven fabricsubstrate 2, a pack agent layer 3 and a liner layer 4, and its center isdirectly fixed onto the packaging film 6 with the hot-melt adhesive 5via its liner layer 4. Another packaging film 6 is laid over thethus-fixed patches 1, and the edges 8 of the resulting package pouch 9are sealed to form the package 10.

As opposed to this, in the prior art technique as illustrated in FIG. 2,the sheet-type patches 11 are prepared by half-cutting a long sheetcomposed of a substrate 12, a pack agent layer 13 and a liner layer 14.In this case, the liner layer 14 is not cut at all, but shall act as thesupport in the package of the patches. The pair of half-cut patches 11are inserted into the package pouch 19 along with the support 14, andthe edges 18 of the pouch 19 are sealed to form the package 20containing the patches 11 therein.

In the package 10 in FIG. 1, the patches 1 are integrated with thepackage pouch 9, and therefore do neither move nor adhere to each other.

However, in the package 20 in FIG. 2, the substrate and the pack agentnot used in the separated patches 11 shall be wasted. In addition, inthis case, the step of half-cutting the long sheet requires strictlycontrolled working conditions. In particular, where the pack agent inthe long sheet contains a water-soluble polymer compound as crosslinkedwith a polyvalent metal, cutting and trimming the patches 11 out of thelong sheet could be effected only after the crosslinking in the packagent layer 13 is fully completed. Therefore, prior to the step ofcutting the patches out of the long sheet, the pack agent layer must befully crosslinked and aged for a long period of time, and, in addition,the cutting step must be followed by the additional step of insertingthe patches into the package pouch 19.

Different from the prior art method, the method of the invention forproducing the package 10 of FIG. 1 does not require any strict workingconditions for cutting the patches, since, in the method, the long sheetfor the patches 1, having the structure of substrate 2/pack agent layer3/liner layer 4, may be completely cut into the patches 1. Even if thepack agent contains a water-soluble polymer compound as crosslinked witha polyvalent metal, the long sheet may be efficiently and easily cutinto the patches 1 before the crosslinking of the compound is not as yetcompleted. Accordingly, for producing the package of sheet-type patchesof the invention, the steps of forming the long sheet for patches,cutting the long sheet into individual patches, fixing the patches ontoa packaging film, and sealing the film into a package pouch can becontinuously effected in one continuous process, therefore, theproduction efficiency in the continuous process is extremely high. Inaddition, the raw materials for the patches 1 are not wasted.

EXAMPLE 2

FIG. 3 shows another embodiment of the package of sheet-type patches ofthe invention; and FIG. 4 shows an apparatus for producing the package.

In this embodiment, a plastic laminate film is used as the packagingfilm 6 to form the package pouch 9. As the packaging film 6, forexample, used is a multi-layered laminate film, which is composed of aheat-sealable, dielectric inner layer 6A of polypropylene (PP), agas-barrier interlayer 6B of Al, and a protective outer layer 6C of PETfor protecting Al. In this, the liner layer 4 of the patch 1 ispreferably an easily chargeable synthetic resin of PET, PP, polyethyleneor the like.

In this embodiment, at least one of the liner layer 4 of the patch 1 andthe inner layer 6A of the packaging film 6 is previously charged, andthe patches 1 are fixed onto the packaging film 6 via the liner layer 4by means of the electrostatic force as generated by the charging.Another packaging film 7 is laid over the patches 1 having been fixedonto the packaging film 6, and the peripheral edges of those films areheat-sealed to form the package pouch 9.

The packages 10 can be produced, for example, in a packaging apparatus30 shown in FIG. 4. The apparatus 30 comprises a sheet feeding device 21via which a long sheet 28 for patches 1 is continuously fed into theapparatus; a cutting device 22 (having an anvil roll 22A and a diecutter 22B) in which the long sheet 28 is cut into patches 1 having adesired shape; a packaging film feeding device 23A via which a packagingfilm 6 is continuously fed into the apparatus; an electrostaticallycharging device 24 (having an electrode 24A) in which the packaging film6 is previously charged; a transfer roll 25 which receives thesheet-type patches 1 having been cut in the cutting device 22, andtransfers them onto the charged, packaging film 6 at predeterminedpositions thereon; a packaging film feeding device 23B via which anotherpackaging film 7 is fed into the apparatus; a heat-sealing device 26(having a side sealer 26A and an end sealer 26B) in which the packagingfilm 7 is laid over the packaging film 6 having the patches I aselectrostatically fixed thereon, and the two films are heat-sealedtogether at the peripheral edges to form the sealed part 8; and acutting device 27 in which the sealed part 8 of the films 6 and 7 is cutat the center of the end-sealed part to produce packages 10.

Various types of charging devices are usable herein as theelectrostatically charging device 24. In one type, a large number ofneedle-like electrodes are brush-wise or comb-wise disposed in thewidthwise direction of the packaging film 6 in such a manner that theyare not in contact with the film 6. In another type, a metal roll iskept in contact with the film 6 in such a manner that its axialdirection is perpendicular to the running direction of the film 6, andthe roll is rotated in accordance with the running motion of the film 6.In still another type, conductive wires or the like are so extended inthe widthwise direction of the film 6 that they are kept in contact withthe full width of the film 6.

The method for producing the packages 10 in the apparatus 30 isdescribed hereinunder.

First, the long sheet 28 having been fed via the long sheet feedingdevice 21 is cut in the cutting device 22 into sheet-type patches 1having a desired shape. The sheet-type patches 1 are then vacuum-wiseattracted by the transfer roll 25 at the side of the non-woven fabric 2of each patch 1.

Meanwhile, the packaging film 6 having been fed via the packaging filmfeeding device 23A is electrostatically charged in the charging device24. In this step, preferably, the inner layer 6A of the film 6 ischarged.

Next, the sheet-type patches 1 having been vacuum-wise attracted to thetransfer roll 25 are fixed onto the charged film 6 at predeterminedpositions by means of the electrostatic force. In this step, thevacuum-suction mode of the transfer roll 25 is switched to a pressureemission mode, whereby the patches 1 are transferred onto the film 6. Inthat manner, the sheet-type patches 1 are fixed onto the inner layer 6Aof the film 6 via the liner layer 4 of each patch 1 by means of theelectrostatic force. The surface of the transfer roll is preferably madeof a conductive metal or the like in order to facilitate the transfer ofthe patches 1 from the roll onto the film 6.

Next, the other packaging film 7 having been fed into the apparatus viathe packaging film feeding device 23B is laid over the film 6 having thepatches 1 fixed thereon, and the two films are heat-sealed in theheat-sealing device 26 at the outer peripheral part to form the sealedpart 8. Subsequently, in the cutting device 27, the sealed part 8 is cutat the center of the end-sealed part to produce packages 10 ofsheet-type patches.

EXAMPLE 3

FIG. 5 shows one preferred embodiment of the shape of the sheet-typepatch to be packaged in the invention.

The sheet-type patch 1 has a horse-beanlike shape, as shown in FIG. 5,which is so formed that the height A falls between 50 and 80 mm, thewidth B in the center part falls between 20 and 30 mm, the depth C inthe concave part falls between 5 and 10 mm, the width D of the concavepart is 40 mm or longer; and the radius of curvature E at the center ofthe concave part falls between 25 and 30 mm.

As having the illustrated shape, the fittability of the patch 1 to theareas outside and under the eyes is improved. In addition, the patch maybe applied not only to the areas outside and under the eyes but also tothe areas around the nasolabial grooves.

EXAMPLE 4

FIG. 6 shows another preferred embodiment of the shape of the sheet-typepatch to be packaged in the invention.

For this embodiment, a pair of nearly L-shaped sheet-type patches 1,which are for skin-care use for treating the areas outside and under theeyes and the areas around the nasolabial grooves, are fixed onto apackaging film in such a manner that they face to each other. Where thepair of such patches are positioned in the illustrated manner, the spacefor the patches may be reduced, and if desired, a plural number of suchpatches may be packaged in one package pouch.
